Abstract

A power plant has a generator (12) that is cooled by hydrogen gas. The power plant (10) has a terminal compartment (14) for housing stator terminals (100) of the generator (12) and conductor (104) connections of a main bus (18) taking electrical power away from the power plant. The power plant has a generator auxiliary equipment compartment (16) that is distinct from the terminal compartment (14). The generator auxiliary equipment compartment (16) receives tap connections (200) that draw power from the main bus (18). The main bus (18) comprises isolated phase bus duct (20), one for each phase. Electrically insulating sealing bushings (110) are located in each phase of the isolated phase bus duct (20) between the connections with the stator terminals (100) and the tap connections (200) to seal against the escape of hydrogen gas from the terminal compartment (14) into the generator auxiliary equipment compartment (16).
